IfItoN erven, MICHIGAN y i if COMBINATION FUSE HoLDE-RND LIGHTER yAppunti@ mea April 21,

This invention relates to ycombined fuse holders and lighters and hasfor the primary object, the provision of a device of the above statedcharacter which is especially adapted for receiving and holding aplurality of explosive fuses regardless of their lengths and having anigniting medium which vwhen lighted will be slow burning and willsuccessively ignite the fuses in accordance with 19 the arrangementthereof in the holder to assure lighting of all of the fuses withmaximum safety to the operator and permit the( operator to easily reacha point of safety or shelter prior to the explosion.

l5 With this and other objects in view, this invention consists incertain novel features of construction, combination and arrangement ofparts to be hereinafter more fully described and claimed.

20 For a complete understanding of my invention, reference isto be hadto the following description and accompanying drawing, in which Fi ure lis a plan view illustrating a combine fuse holder and igniterconstructed in accordance with my invention.

Figure 2 is an edge elevation illustrating the same with the igniterremoved.

Figure 3 is a sectional view taken on the line 3 3 of Figure 2.

Figure 4 is a transverse sectional view taken on the line 4 4 of Figure1.

Figure 5 is a similar view taken on the line 5 5 of Figure l. Y

Figure 6 is a fragmentary sectional view taken on the lineG- of Figurel.

Referring in detail to the drawing, the numeral l indicates a holdercomprising a pair of relatively spaced plates 2 which have their endsoffset inwardly and secured to-V gether by rivets 3. Rightangularlyextending flanges 4 are formed on the edges of the plates and the iangesof one plate extend-in corresponding direction and in oppositedirections to the flanges of the other plate. Hooks 5 are carried by theends of the holder and removably support an igniting medium 6 preferablyconstructed from a slow burn- A .ing composition. The igniting mediumis4flattened throughout ay portion thereof and 1932'. s riai' No. 606,711."f y Y "f E, disposed.V opposite one edge of the holdenl whiletheremaining portion ofy the igni'ting medium is of rod shape' andprojects a coni siderable, distancel beyondA ,oneV end ofl the-v holderfor the purpose of being ignited .by the I5 operator. vThe, rodshaped'portion of the;

igniting medium is comparatively slowburning, Vwhile the flattenedportion ofthe igniting lmedium is capable ofproducing-.sunlicientvflame' to assureY the igniting of fuses 7 pcarried by theholder.. I v i `Retaining tonguesV 8 are. struck inwardly.from the plates2 and havetheir free -efdges serrated-as shownat 9 forthepurpose of permitting the `.fuses 7 to be'readily'insertedb'ef'vtween theplatesbut which willprevent accidental removal of thefuses-'from the holder dueto the serrations biting intol the fuses las f.shown infFigure 4. referring to the k drawing it willbe Yseen that 4aplurality of fuses may be accommodatedv within the holder and that thefuses can be secured in place to be'ignited by the burning of theignitiony medium regardless of theirlengths. f

f or a number o f years it has been common practice in mining work tousesafety fuses and blasting caps .to lire or ,ignite high.4 explosives.The.' fusesy are lout in v di'erent lengths so that the charged holeswill lbe y exploded in theorder wanted and asit is SCE/lit necessarythatthe center or cutting in holes explode beforethe others, the lengths of.the fuses for these holes are naturally shrter` thanthe others; Thellemgths of all fuses, however, must be long enough to allow Ithe 8%@operator afterlighting the ignition ,I nedi'urnl sufficient time to seekshelter from the blast, the burning speed of ordinary fusesv beingapproximately two feet perminute, and it will bevreadily seen that theshortest fuses 9%@ cannot Vsafely be lessl than three feet in lengthwhich allows thirty seconds for lighting theV fuses and then one minutefor the operator to reach a place of safety, however,'in many instancesa greater time should be afforded V9?? the operator to reach a point ofsafety and which can be easily accomplished by increasing the lengths ofthe Vfuses. `The ends of the different fuses areplaced in the holder inthe order thattheholes are to be lired,

` ignaro@ in. other words, the shortest Jfuses are placed in the holderat the end Where the re fromJ the igniting 'medium will strike first,the other fuses being .placed beyond the shortest one in the 'order offringand in this way the fuses for the cutting in holes arelit beforeythe others and due to the different lengths of the fuses theyr will-firethe'eX-plosives inA the order desired. A device of this charactern)provides maximum` safety and permits `one person to lightsei'fera-l'times the number ci holes than formerly and with maximum safety. `It vis to be understood that the holder. may be varied in lengthtosuit various min- I ing conditions wherein the number of fuses employedvary.

While' have shown and described the preferred embodiment'o my invention,it will be understood that minor changes in construc-y tion, combinationand arrangement of parts may be made without departingfrom. the spiritand scope of my invention, as claimed.k Havingl thus described myinvention,` what I claim is je 1. A holder comprising spaced'platesfixed together to receive therebetween a plurality of' fuses with theirigniting ends arranged in alignment, tension tongues 0n saidr plates andgripping the fuses, and a. burnable Ineage dium carried by'saidplatesand arranged in close proximity to the igniting ends of saidfuses.

2. A. holder comprising spaced'plates fixed together and receivingtherebetween a plu- `vrality of relatively spaced fuses with theirigniting ends exposed and arranged in alignment With each other,resilient tongues struck from said plates and having serrated edges n tobite into the fuses, and a slow burnabl'e me.

dium carriedl by said plates to ignite the fuses. p

3. A holder comprising spaced plates fixed together and receivingtherebetween a plurality of relatively spaced fuses with their .i tigniting ends exposed and arranged in alignment with each other,resilient tongues struck fromsaid plates and having serrated edges tobite into the fuses, hooks carried by the ends of said plates, and aslow burnable medium removably supported by the hooks lying in closeproximity to the fuses and projecting a desirable distance beyond oneend of said plates to be ignited. 55 In testimony whereof I aiiiX mysignature.
